DISPENSING D EvIdE FOR SODA-FOUNTAINS.

To all whom it may concern: 7

Be it known that we, WILLIAM H. BECKER and CHARLES W. STEED, both citizens of the residing in the have invented certain new and useful Imrovements in Dispensing Devices for Sodaountains, of which the followin is a full,

clear, and exact description, re erence be ing had to the accompanying drawings, forming part of this specification.

ur invention relates to a dispensing device for soda fountains, the invention having for its object to provide a device of this de scription having a single spout and means for controlling the discharge through said spout of either a mixture of syrup and carbonated water, syrup alone, or carbonated water alone, thereby producing a dispensing device which, although ofsingle type, has a multiple of functions.

Figure. I is a top dispensing device wlth the-top cap in. horizontal section and the retaining screw above the operatinglever omitted, the parts of the device being in the positions assumed when both of the cylinders are free to rotate in conjunction with each other. Fig. II is a similar view to Fig. I, with the parts in the positions assumed when the-outer valve is held in a stationary position by the locking device provided for holdin it. Fig. III is a perspective view of the locking bolt for holding the outer valve. Fig. IV is a vertical sectionthrough the dispensing device. Fig. V is a horizontal section taken on line VV Fig. IV. Fig. VI is a vertical section through the lower end" of the device with the port containing portion ofthe inner valve shown in elevation. Fig. VII is a fragmentary View of the outer shell showing a portion of the flavor indicator.

In the accompanying drawings :'1 designates the outer shell of our dispensing device which is provided at its upper end with\ a rim 2 and in the inner face of which are notches 3 ada her to be heremafter specifically referred to. 6 is a discharge spout detachably con nected to the lower endof the connection between these members" being p refefgbly a screw threaded one, as seen in 1 l n the shell isa plurality of openings 4 that are adapted to receivesyrup conducting pipes 7 that may lead from any desirable or plan view of ourted to rece'iv'ea locking memshell 11, the

source of supply of syrup. In the shell is carbonated water may be conducted from any source of supply to be delivered into the header and pass therefrom through the ducts 5, the de very of carbonated water from the ducts being controlled, however, by members within the shell 1, as will hereinafter appear. The pipes 7 and 9 are incased adjacent to the shell 1 Within the housing 10 located between the shell and the chamber 11 from which the ipes extend.

12 is a cap loosely mounted on the shell 1 to turn thereon, the cap being provided with a depending flange that surrounds the rim 2 in the upper end of the shell.

. 13 designates an outer valve that is snugly fitted within the shell 1 and is adapted to be and chambered interiorly and in'the wall of the valve is a duct 1Q adapted to be placed in communication with either of the syrup conducting pipes 7 leading to the shell 1, and also a duct 15 adapted to be placed in communication with any one of the ducts 5 to which carbonated water is delivered from the header 8. The valve 13 has a screw threaded lower end thatreceives an adjusting or take up nut 16 which is adapted to bear against the lower end of the shell 1 when rotated upon thethreaded lower end of the valve and whereby said valve is caused to be properly fitted withinthe shell.

The valve 13 is provided with a top plate 17 secured to the body of the valve in any suitable manner and in which is a central aperture 18. The top plate 17 comprises acentral member which 15 cut awayat 19, an outer ring member 20containing notches 21 and 22 located diametrically opposite each other, and stop members 23 interposed between the ring member and the central rounding the central member and between it and the ring member except at the locations of the stop members 23.

26 designates an inner valve corresponding in shape to the shape of the outer valve, .13 and located within said outer valve, but

said inner valve beingmaintained with a proper fit within said outer valve by an admember. There 1s a circular channel 24 sur- I extended from a duct lea-din wallet the inner valve and w ich is a'dapt- .30

justment or take-up nut 27 fitted to. the' duct 14 in the outer valve and a duct 32: to register .with the duct 15 in saidj outer valve, the two ducts 31 and 32 being adapted located in vertical alinement, with the obj ect in View of providing under certain conditions to be hereinafter made plain for simultaneous delivery of syrup and carbonated wvater through the ducts 31 and-32 into the chamber in the inner valve 26 to pass from said chamber and to discharge through the spout 6. The inner valve is also pro-' vided with a syru 25 conducting nozzle 33, (see Figs. V and 1'), extending from its wall to the center of the chamber in the inner valve, the duct in said nozzle being through the ed to be placed in communication with the duct 14 in the outer valve at a time when the ducts 31 and 32 are not in communica: tion with the ducts 14 and 15 in the outer valve, or with any syrup conducting pipe 7 or the carbonated water conducting pipe 9, at which the nozzle 33 is adapted to be placed in communication with any particular syrup conducting pipe 7 when the duct, therein 1s in registration with the duct 14' and said duct 14 is opposite to'the pipe 7 from which it may be desired to occasion flow of syrup to said nozzle to bedischarged 'from the lower end of the nozzle into and through the spout 6.

outer and inner valves 13 -andfl.26 may be operated and which is provided with a 34de'signates ahand lever by" which the handle 35 that pro'ects outside of the shell and cap of the ispensing device. This lever is arranged horizontally immediately above the top late 17 of the outer valve and is provided with a slot 36 extending longitudinally thereof within which then'onacircu'lar head 30 of the stem 29 extendmg :E-rom the inner valve is located. Provision is thereby made for rotation of the inner valve through the mediumof the hand I front of the device lever "and also for longitudinal movement of the hand lever with'an ebjeet in view whichwill presently be made plain. The hand "lever carries a lu 37 located at the and which is adapted to be moved into and out of the notch 21 in the r' member 20 o=the outer valve top plate At the bottom of the hand lever is conducte and near its rear end is a segmental shaped "shifter 38 which is secured to the lever and is adapted to operate in the channel 24 in the outer valve top plate.

39 is a locking boltrestjng upon the top plate of the outer valve in the cavity prouced by the channel 24 and the recess at 19.

This locking bolt is operable in the notch 1 22 in the ring member 20 of the valve top plate and its. rear end is arranged in a pocket 17 in the central portion of-the cap plate within which said rear end is always confined to provide for the locking bolt be ing guided when it is moved longitudinally. The locking bolt is provided with a notch 40 that receives the segment shaped shifter 38 through the medium of which the bolt is moved into and out of o erative positions for service to be explained) a The hand lever 34 is provided with a pointer 41 that is adapted to move around the external surface of the shell of the dispensing apparatus and which traverses an indicator 42 mounted upon the shell and which bears the names of the syrups or flavors it may be desired to dispense from a soda fountain equipped with our dispensing device.

The operation of our dispensing device is as follows: One of the main objects in view in this dispensing device is to provide for simultaneous flowiinto and through'the dispensing device of both syrup or flavor 1 liquid and carbonated water mixed in proper proportions with the result of guardmg agalnst the operator dispensing at one time too great an amount of either kind of liquid, and at another time too small an amount of either kind of liquid. With this in view, the valves 13 and 26 are adapted to be so adjusted that there .mayoccur simul taneous flow into the chamber in the inner valve 26 through the ducts 31 -and .32 when placed in communication through the ducts 14 and 15 in the outer-valve with a syrup conducting pipe 7 and a duct 5 leading from the header '8. with-=which the carbonated water conducting ipe 9 communicates. To 'so adjust said va' ves, the hand lever 34 is operated as follows: It will-be amumed first that the hand lever and its carried parts are in the positions illustratedin Figs. 1 and 1V,

at which time the locking bolt 39 is withdrawn from any notch 3 atthe upper -@end of the shell 1, and' the lug 37 at the bottom of the hand lever is positionedv in the notch .21. The operator-now moves thehand lever to "impart rotation to both of the valves :13 and '26 until'the pointer 41 is brought to a position to indicate upon the indicator 42 the flavor it is desired to dispense through the dispensing device, and at which time the duct 14 W111 be in alinement with the s rup conducting: ipe ,7 through which said aver The duct-14in the outer valve will also at this time be in communication through one of the ducts with the header 8 from which carbonated water is supplied.

until the ducts 31 and 32 in the'inner valve 7 14 and 15 in the outer valve and simulta-' There is no communicationestablis ed at this time through the inner valve by reason of'the fact that the ducts 31 and 32 therein are out of registration with the ducts 14 and 15, but such communication is established following the nextoperation which involves a shifting of the hand lever 34 to prevent rotation of the outer valve so that the registration of the ducts 14 and 15 with the pipe 7 and the duct 5 may be retained,

and the inner valve be rotated-independ-' ently of the outer valve. Inperforming the action just referred to, the operator first -moves the hand lever longitudinally in a backward direction whereby the locking bolt operating member 38 carried by the hand lever is caused to move the locking bolt Ion 'gitudinally to set it in one of the notches 3 and provide forits exerting a holding action upon the outer valve. The inner valve is then rotated by turning the hand lever, while the outer valve remains stationary are brought into registration with the ducts neous flow of liquid from the pipe 7 and the header 8 into the chamber of theinner valve is established, this registration being main- 7 tained until thedesired quantity of liquids hand lever from the notch 21in the top plate of the outer valve so that said lugmay move in an arc of a circle inthe channel 25.

It isdesired insome instances to dispense v syrup without dispensing carbonated water therewith and it is for this reason that we provide a nozzle 33 carried by the inner valve and arranged aside from the ducts 31 and 32. There is no du'ct in the inner valve registerable with said nozzle through which carbonated water may be discharged when syrup is discharged through said nozzle and, as a consequence, when the duct 14 in the outer valve is brought into registration with thesyrupconducting pipe and the duct in the nozzle 33 is thereafter brought into registration with said duct 14, there will be a discharge of syrup only from the dispensing device t rough its spout 6. y
